Morbilidad por trastornos del movimiento en la consulta de Neurología Morbidity due to movement disorders in the Neurology Department
Mónica Rodríguez Montalbán,Osiel Gámez Rodríguez,Tania Hernández Silva,Sergio Echavarría Danger
MEDISAN , 2012,
Abstract: Se realizó un estudio observacional, descriptivo y transversal de 175 pacientes con trastornos del movimiento que asistieron a la Consulta de Neurología del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" desde el 2007 hasta el 2010, con vistas a describir la morbilidad en estos. Dichas afecciones iniciaron durante la quinta y sexta décadas de la vida en la mayoría de los integrantes de la casuística, con una frecuencia superior de la enfermedad de Parkinson, el temblor esencial y las distonías, y prevalencia del sexo masculino y el color de la piel mestizo. La electromiografía de los músculos agonistas y antagonistas evidenció el predominio del temblor de reposo y la disfunción en la inhibición recíproca, sobre todo en la enfermedad de Parkinson. An observational, descriptive and cross-sectional study of 175 patients with movement disorders who attended the Neurology Department in "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital was carried out from 2007 to 2010, aimed at describing the morbidity in them. These disorders began during the fifth and sixth decades of life in most of the members of the case material, with a higher frequency of Parkinson disease, the essential tremor and dystonias, and prevalence of the male sex and half-bred skin. The electromyography of the agonistic and antagonistic muscles evidenced the prevalence of the rest tremor and the disorder in the reciprocal inhibition, mainly in the Parkinson disease.

Susceptibility of Solanum phureja (Juz. et Buk.) to Potato yellow vein virus
Guzmán,Mónica; Rodríguez,Patricia;
Agronomía Colombiana , 2010,
Abstract: sixty two virus-free accessions of solanum phureja from the colombian central collection of this tuber (bogotá-soacha) were tested for their susceptibility to infection with potato yellow vein virus (pyvv). under greenhouse conditions, the plants were inoculated with pyvv using viruliferous trialeurodes vaporariorum (westwood) whiteflies, and monitored for three months (the tuber formation period of s. phureja) for symptoms of infection and virus capsid protein (cp) production, by means of a reverse transcription-polymerase chain reaction (rt-pcr) assay. symptoms of pyvv infection, consisting in the chlorotic flecking of leaflets, followed by complete vein yellowing, were noted in 38 accessions whose rna extracts generated correct-sized cp amplicons in rt-pcr assays. thirteen of the remaining accessions were found to be latently infected with the virus through positive rt-pcr assays. twelve accessions were free of virus infection as judged by the absence of symptoms and negative rt-pcr assay results over two cycles of tuber setting and germination. these accessions may possess field resistance to pyvv. this work is the first one to detect and define the levels of susceptibility of colombian s. phureja accessions to pyvv infection, and to identify the potential existence of resistance to this deleterious andean potato virus.

Rodríguez Fontal,Mónica; Rondón Espín,Auristela;
Revista de la Facultad de Medicina , 2000,
Abstract: we did a research on cholesterol and triglyceride levels in 192 teenagers, 12 to 18 years old. besides, we investigated the relationship among family backgrounds on cardiovascular illnesses and hypercholesterolemia, daily tv hours watching and corporal mass index and serum lipid levels. hypercholesterolemia frequency was 22.2%, while hipertriglyceridemia was present in 12% of the teenagers. no statistically significant difference was found in the levels of cholesterol and triglyceride between teenagers with positive family background and those lacking antecedents (p < 0.05). in patients who said to watch tv more than 5 hours a day, tendency was to higher levels of cholesterol and triglycerides. in those with bigger corporal mass index, significantly higher triglycerides levels were found ( <0.05).
Hipercolesterolemia en la Población Adolescente

Revista de la Facultad de Medicina , 2000,
Abstract: Se realizó una investigación con la finalidad de conocer los niveles de colesterol y triglicéridos de 192 adolescentes entre 12 y 18 a os de edad. Además, se determinó la relación entre los antecedentes familiares de enfermedades cardiovasculares e hipercolesterolemia, horas de televisión al día e índice de masa corporal, y los niveles de lípidos séricos. La frecuencia de hipercolesterolemia fue 22,4%, mientras que la hipertrigliceridemia se reportó en 12% de los adolescentes. No se encontró diferencia estadísticamente significativa en los niveles de colesterol y triglicéridos entre los jóvenes con antecedentes familiares positivos y aquéllos que carecían de antecedentes (p<0,05). En los pacientes que manifestaron ver más de 5 horas de televisión al día, se observó la tendencia a presentar mayores niveles de colesterol y triglicéridos; y en aquéllos con un índice de masa corporal elevado, se observaron cifras de triglicéridos significativamente superiores (p<0,05). We did a research on cholesterol and triglyceride levels in 192 teenagers, 12 to 18 years old. Besides, we investigated the relationship among family backgrounds on cardiovascular illnesses and hypercholesterolemia, daily TV hours watching and corporal mass index and serum lipid levels. Hypercholesterolemia frequency was 22.2%, while hipertriglyceridemia was present in 12% of the teenagers. No statistically significant difference was found in the levels of cholesterol and triglyceride between teenagers with positive family background and those lacking antecedents (p < 0.05). In patients who said to watch TV more than 5 hours a day, tendency was to higher levels of cholesterol and triglycerides. In those with bigger corporal mass index, significantly higher triglycerides levels were found ( <0.05).

Guzmán,Mónica; Román,Verónica; Franco,Liliana; Rodríguez,Patricia;
Agronomía Colombiana , 2010,
Abstract: la colección central colombiana (ccc) de papa en campo puede ser blanco de fitopatógenos. en el a?o 2008 se estableció la prevalencia de los virus potato virus x (pvx), potato virus y (pvy), potato leafroll virus (plrv), y potato virus s (pvs) en muestras de un grupo de 581 accesiones de papa (solanum l. sect. petota dumort) mantenidas por la corporación colombiana agropecuaria (corpoica). folíolos de dos plantas por accesión se expusieron a anticuerpos comerciales específicos (agdia) haciendo uso de las técnicas elisa-das o dasi. el 98,8% de todas las muestras analizadas arrojó resultados positivos para al menos uno de los cuatro virus, en diferentes porcentajes para cada uno de ellos. pvs se detectó en el 85% de las accesiones, seguido de plrv (77,4%), pvy (58,6%) y pvx (13,9%). en el 44% de las muestras de los grupos chaucha y phureja se detectaron sólo dos de los virus evaluados; en el 40% de las accesiones de los grupos tuberosum y andígena se encontraron tres virus; y en el 21% de las muestras del grupo tuberosum se observaron cuatro de ellos. se encontró una alta prevalencia de infección viral simple y mixta en las accesiones analizadas (aproximadamente 50% de la colección estudiada). esta incidencia infecciosa puede ir deteriorando la calidad y cantidad de estos tubérculos. pocas accesiones (1,2%) arrojaron resultados negativos para los cuatro virus. sin embargo, cabe se?alar que no se analizaron todas las plantas disponibles para una misma accesión, lo cual impide afirmar que los resultados son concluyentes. a pesar de ello, estos son importantes para las instituciones y programas interesados en la conservación de recursos genéticos y el mantenimiento de la diversidad de solanum l. sect. petota dumort en colombia

NURE Investigación , 2006,
Abstract: The importance of the approach between the service of primary attention (AP), and the service of specialised attention (AE) states the necessity of establishing mechanisms which integrate both systems. The objective of this study is to evaluate the usefulness perceived by internal and external users related to the nursing reports on hospital discharges, elaborated by the AE nurses and sent to AP professionals.A transversal descriptive study had been made whose study sample were patients, AE nurses belonging to the hospitalisation units, and AP nurses from all the health centres in Area III. In order to achieve this, the required questionnaires were made using ordinal qualitative variables.The obtained results identified that AP nurses considered 60,86% as normal the period of time between the sending of the report and its reception.The presence of nursing diagnosis expressed in NANDA taxonomy in the edited report was positively accepted by 43,47% among AP nurses, and 53,84% among AE nurses. Both professionals coincide in the elaboration of the report considering it essential or very important (78,25% AP; 73,07% AE)The same way, 65,38% of hospital nurses consider essential or very important making public an AP report for patients admitted in a programmed way. In relation to patients and their main caretakers, 94,28% of patients considered that the report was properly explained to them when handed out, and also 96,87% confirmed that the given information was useful and easy to understand.As a conclusion we could say that both groups confirm the necessity and usefulness of a nursing report after being discharged from hospital, which contributes to a better continuity and equality in the nursery care.
Efecto de aplicaciones foliares de metanol sobre el rendimiento de lechuga (Lactuca sativa L.)
Mónica Solari,Alfredo Rodríguez Delfín,Sven E. Jacobsen,Hugo Soplín
Ecología Aplicada , 2004,
Abstract: Anteriores investigaciones, sugieren una incorporación por las plantas del carbono proveniente del metanol; por ello se dise aron experimentos para determinar si su aplicación foliar afectaría el rendimiento y crecimiento en un cultivo hidropónico de lechuga (Lactuca sativa L.). Se utilizó metanol a los porcentajes de 10, 20, 30, 40, 50, 60, 70 y 80, con un testigo sin tratamiento. Se midieron el peso fresco, longitud del tallo floral, apertura estomatal y se anotaron otras observaciones correspondientes. Hubo variaciones estacionales, probablemente debido a las diferentes tasas de crecimiento vegetativo y de almacenamiento a lo largo del a o, originadas por cambios de temperatura y luminosidad. A la cosecha, se registraron incrementos de peso radicular con las aplicaciones foliares de metanol, pero no incrementos de peso foliar. También se pudo observar aumento en la elongación del tallo floral en los tratamientos con máximas aplicaciones de metanol. No se pudo comprobar efectos sobre la apertura estomatal.
Dynamics of DNA methylation and Histone H4 acetylation during floral bud differentiation in azalea
Mónica Meijón, Isabel Feito, Luis Valledor, Roberto Rodríguez, María Ca?al
BMC Plant Biology , 2010, DOI: 10.1186/1471-2229-10-10
Abstract: The results of this work indicate that epigenetic mechanisms such as DNA methylation and histone H4 acetylation have opposite and particular dynamics during the transition from vegetative to reproductive development in the apical shoots of azalea. Global levels of DNA methylation and histone H4 acetylation as well as immunodetection of 5-mdC and acetylated H4, in addition to a morphological study have permitted the delimitation of four basic phases in the development of the azalea bud and allowed the identification of a stage of epigenetic reprogramming which showed a sharp decrease of whole DNA methylation similar to that is defined in other developmental processes in plants and in mammals.The epigenetic control and reorganization of chromatin seem to be decisive for coordinating floral development in azalea. DNA methylation and H4 deacetylation act simultaneously and co-ordinately, restructuring the chromatin and regulating the gene expression during soot apical meristem development and floral differentiation.In the ornamental plant industry, azalea production represents a cultivation in expansion. For commercial purposes azalea plants must be compact and well branched [1], although floral quality is the fundamental trait for the commercial success of these species. The flowering promotion, by both increasing the number of flowers and advancing the time of flowering, as well as creating novelty in the flower structure, are major desirable traits in ornamental plant breeding.The annual cycle of azalea japonica in Asturias (Spain, Europe) involves a period of vegetative active growth from May to September, followed by an apparent rest from October to January, months in which well formed buds are visible. As from January, the floral buds are developed, culminating in March with full bloom. Authors such as Bodson [2] defined four phenological stages in the flower development of azalea:1) transition of the apex from the vegetative to floral condition; 2) development of
